Output power description:
Output power=Input voltage * 20A, for example: Input voltage 12V, 12V * 20A=240W. The maximum power at 12V input is 240W
For example, when 24V * 20A=480W is input, the maximum power is 480W when 24V is input,
For example: Input 36V, 36V * 20A. At this time, the power is 720W, which exceeds the power of the power supply. At this time, the input current cannot exceed 13.8A
Output voltage/output current regulation/input low battery protection regulation
Voltage regulation: When the power is turned on and there is no load, use a flathead screwdriver to adjust the output terminal "RV2" potentiometer (indicated in the figure below) clockwise to lower and counterclockwise to increase. Due to the large capacity of the output capacitor, the response time when adjusting the output voltage from high voltage to low voltage will be relatively slow. The amplitude of the instrument adjustment is smaller.
Current regulation: Turn the "RV3" potentiometer clockwise for about 30 turns, set the output current to the minimum, connect the LED or battery, and turn the "RV3" potentiometer counterclockwise to the desired current. For battery charging, after the battery is discharged, it is connected to the output and adjusted to the current you need. When charging, it must be adjusted after the battery is discharged base note. (Do not adjust the current by short circuit output. The circuit structure of the boost module cannot be adjusted by short circuit,
Input low battery protection regulation: Low battery protection is mainly aimed at preventing battery overdischarge and damage to the power module and battery caused by low battery voltage when the input power source is a battery. For example, setting low battery protection for 12V batteries. Connect a 10V voltage to the input terminal of the power module and use a Phillips screwdriver to adjust RV1 (clockwise to increase the voltage value of the protection point, counterclockwise to decrease the voltage value of the protection point) until the "undervoltage" indicator light is on. At this time, the low battery protection voltage is 10V. When the battery voltage drops to 10V, the power module does not rise (the input voltage is equal to the output voltage)
matters needing attention:
1. This power supply is a boost power supply, which can only boost and cannot be used for voltage reduction. The output voltage can only be higher than the input voltage. When the input voltage is higher than the set output voltage, the output voltage is as high as the input voltage.
When used for constant current charging, it is necessary to ensure sufficient input and output voltage difference. For example, when inputting 12V, only batteries above 24V can be charged, and batteries below 12V cannot be charged. If the input power is 24V, only batteries above 36V can be charged, and batteries below 36V cannot be charged.
3. The input current should not exceed 20A during use. (Input current calculation formula: Output power/Input voltage * 1.05=Input current. For example, if the input is 12V, the output is 36V, and the output is 8A, the input current=(36V * 10A/12V) 1.05=Input current 31.5A. This has exceeded 20A and is not allowed.)
4. Strengthen heat dissipation when working at full load for a long time
5. The input power cannot exceed 500W (power: input voltage * input current)
6. It is strictly prohibited to short-circuit output and adjust current
When selecting a power supply, the power of the power supply should be more than 1.5 times the load power
